Over the past two decades plenty of resonant and quasi-resonant converters have been developed and proposed as an answer to the difficulties raised by square-wave converters, especially those related to their parasitic elements. The basic idea is to put these parasitics in use. The core of both classes of converters is a tank circuit. Unlike resonant converters, where it takes part actively in ...

In this paper, a review of PV inverters is reported based on converter characteristics as the number of energy processing stages, the presence of a transformer (high-frequency or 50Hz transformer), and the adopted configuration of the PV field. In particular, the considered solutions have been evaluated depending on efficiency, input current ripple and life-time of the capacitors coupling with ...

Considering the effects of isolation and high efficiency, a series-resonant DC-DC converter (L-L-C type, with two inductors and a capacitor) has been introduced into a residential photovoltaic (PV) generation and storage system in this work, and a voltage gain curve upwarp drifting problem was found. In this paper, the reason of upwarp drifting in the voltage gain curve is given, and a new chan...

The series-resonant converter is one of the major classes of electronic power converters that are extensively applied in dc-dc conversion. This technology transfers bulk energy efficiently through a series-resonant circuit in the direct path of the energy transfer. This resonant converter forms a high-frequency ac link between the voltage sources connected to the input and output terminals. The...

Abstract: In this work, a unidirectional full-bridge resonant converter with secondary-side phase-shifted control is addressed. With the variation of voltage gain and power level, this converter may enter into different operational modes, including three continuous current modes and one discontinuous current mode. The details in each operation mode are discussed one by one. The boundary conditi...

This paper presents a study of resonant converter topologies targeted for CMOS integration. An improved new method to design efficient monolithic Quasi-Square-Wave converters is proposed.

Based ...

This paper presents design of generalized resonant dc/dc converter with class E oscillator and a experimental result for low output Q and finite dc-feed inductance are shown. Low Q and finite dc-feed inductance is effective to minimize the circuit scale. Therefore, it is required to design the converter with any conditions, i.e., low output Q and finite dc-feed inductance. The experimental meas...

This paper presents the operational characteristics of a high voltage flyback converter with resonant elements. In high voltage low power applications, the effect of a transformer’s stray capacitance might be the most important factor that influences the overall performance of the circuit. A detailed mode analysis and the design procedure are presented in designing the high voltage flyback conv...

A new zero voltage switching (ZVS) dc / dc converter operating on constant frequency and having wide linearity is proposed. ZVS operations are achieved not only for the primary switches but also for the secondary rectifier diodes to reduce the switching stresses and losses. The proposed converter also overcomes the other shortcomings of the conventional resonant dc / dc converters such as high ...
